Description
Technical Field
[0001] The utility model relates to the technical field of door and window accessories, in particular to an outward-opening upper-hung eccentric handle for a door and window. Background Art
[0002] The handle of an outward-opening top-hung window refers to a hardware accessory installed on an outward-opening top-hung window to control the opening and closing of the window sash. By rotating the handle, the transmission hardware mechanism can be driven to realize the two opening modes of the window sash: outward opening and top-hung. The handle not only has an operating function, but also directly affects the safety, sealing and service life of the window. The handle of an outward-opening top-hung window usually consists of a handle body, a transmission rod and a connector. The handle body is the part that the user directly contacts, and its design must conform to ergonomic principles and be easy to operate. The transmission rod is responsible for converting the rotational motion of the handle into the opening or closing action of the window sash. The connector ensures a stable connection between the handle and the window sash.
[0003] Currently, the handles of outward-opening and top-hung windows on the market are basically crooked handles, which have two defects: 1. When the crooked handle is pushed upward, it will hit the profile and is difficult to operate; 2. When in use, it is locked when it is pushed upward and hung when it is pushed downward, which is contrary to normal operation. Utility Model Content
[0004] The utility model aims to provide an eccentric handle for hanging outside doors and windows, so as to solve the technical problem that the existing handle is locked upward and opened downward, which is contrary to the conventional operation.
[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0013] Preferably, the sliding protrusion is fixedly connected to the guide side plate, and a plurality of ridges are arranged on the surface of the sliding protrusion.
[0014] Beneficial effects of the utility model:
[0015] (1) The rotation direction of the driving handle is opposite to the transmission direction of the square shaft of the lock body. When used on the outer opening and lower hanging, it can be locked normally downwards, and when used on the upper hanging upwards; the driving handle is a straight handle eccentric design, which does not hit the profile when operating upwards, and is easy to operate without getting stuck, thereby enhancing its practicality.
[0016] (2) When the handle is not in use and is to be used normally, the guide side plate and the guide slide plate slide downward to separate the locking teeth from the drive gear, thereby ensuring the normal rotation of the drive gear. When the handle is not in use and is to be prevented from being opened by children due to misoperation, the sliding protrusion is pushed upward to push the locking teeth into the tooth grooves of the guide drive gear, thereby locking the drive gear and achieving a safety lock to prevent children from opening the door or window.
